If this fee is paid to the EPO as RO, it must be paid in euros. Due to changes in the exchange rate between the euro and the Swiss franc, the equivalent amount is changed from time to time.

The amounts payable in respect of the international filing fee, the search fee and the transmittal fee are those applicable on the date of receipt of the international application.
